In the new issue of Regulation, economist Pierre Lemieux argues that the recent oil price decline is at least partly the result of increased supply from the extraction of shale oil. The increased supply allows the economy to produce more goods, which benefits some people, if not all of them. Thus, contrary to some commentary in the press, cheaper oil prices cannot harm the economy as a whole.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

But not every politician is blindly ideological like Obama. Vitor Gaspar, Portugal’s Finance Minister, is willing to admit error. Here are some relevant excerpts from a New York Times report.

Mr. Gaspar, speaking to The New York Times last week, has a message for observers who say Europe needs to substantially relax its austerity approach: We tried stimulus and it backfired. Like some other European countries, Portugal tried what Mr. Gaspar called “a Keynesian style expansion” in 2008, referring to a theory by economist John Maynard Keynes. But it didn’t turn things around, and may have made things worse.

Why does the Portuguese Finance Minister have this view? Well, for the simple reason that the economy got worse and more spending put his country in a deeper fiscal ditch.

The yield on Portuguese government bonds – more than 11 percent on longer-term bonds — is substantially higher than the yields on debt issued by Ireland, Spain or Italy. …The main fear among investors is that Portugal is going to have to ask for a second bailout from the International Monetary Fund and the European Union, which committed $103 billion of financial aid in 2011.

(This blog post first appeared at Cato@Liberty following the release of the 2006 Medicare and Social Security trustees’ reports. I repost it, with updated links and “exhaustion dates” because sadly nothing else has changed.)

Year after year, federal officials speak of the Social Security and Medicare trust funds as if they were real. Yesterday Today, the government announced that the Social Security trust fund will be exhausted in 2040 2033 and that the Medicare hospital insurance trust fund will be exhausted in 2018 2024— projections that the media dutifully reported.

But those dates are meaningless, because there are no assets for these “trust funds” to exhaust. The Bush administration wrote in its FY2007 budget proposal:

These balances are available to finance future benefit payments and other trust fund expenditures—but only in a bookkeeping sense. These funds…are not assets…that can be drawn down in the future to fund benefits…When trust fund holdings are redeemed to pay benefits, Treasury will have to finance the expenditure in the same way as any other Federal expenditure: out of current receipts, by borrowing from the public, or by reducing benefits or other expenditures. The existence of large trust fund balances, therefore, does not, by itself, increase the Government’s ability to pay benefits.

This is similar to language in the Clinton administration’s FY2000 budget, which noted that the size of the trust fund “does not…have any impact on the Government’s ability to pay benefits” (emphasis added).

I offer the following proposition:

If the government knows that there are no assets in the Social Security and Medicare “trust funds,” and yet projects the interest earned on those non-assets and the date on which those non-assets will be exhausted, then the government is lying.

If that’s the case, then these annual trustees reports constitute an institutionalized, ritualistic lie. Also ritualistic is the media’s uncritical repetition of the lie.

Unfortunately, some people misinterpret the insights of the Laffer Curve. Politicians, for instance, tend to either pretend it doesn’t exist, or they embrace it with excessive zeal and assume all tax cuts “pay for themselves.”

That’s the theory of the Laffer Curve. What about the evidence? Where are the revenue-maximizing and growth-maximizing points on the Laffer Curve?

Well, ask five economists and you’ll get nine answers. In part, this is because the answers vary depending on the type of tax, the country, and the time frame. In other words, there is more than one Laffer Curve.

With those caveats in mind, we have some very interesting research produced by two economists, one from the Federal Reserve and the other from the University of Chicago. They have authored a new study that attempts to measure the revenue-maximizing point on the Laffer Curve for the United States and several European nations. Here’s an excerpt from their research.

Figure 6 shows the comparison for the US and EU-14. …Interestingly, the capital tax Laffer curve is affected only very little across countries when human capital is introduced. By contrast, the introduction of human capital has important effects for the labor income tax Laffer curve. Several countries are pushed on the slippery slope sides of their labor tax Laffer curves. …human capital turns labor into a stock variable rather than a flow variable as in the baseline model. Higher labor taxes induce households to work less and to acquire less human capital which in turn leads to lower labor income. Consequently, the labor tax base shrinks much more quickly when labor taxes are raised.

There’s a bit of jargon in this passage, so here are the charts from Figure 6. They look complex, but here are the basic facts to make them easy to understand.

The top chart shows the Laffer Curve for labor taxation, and the bottom chart shows the Laffer Curve for capital taxation. And both charts show different curves for the United States and an average of 14 European nations. Last but not least, the charts show how the Laffer Curves change is you add some real-world assumptions about the role of human capital.

Some people will look at these charts and conclude that there should be higher tax rates. After all, neither the U.S. or E.U. nations are at the revenue-maximizing point (though the paper explains that some European nations actually are on the downward-sloping portion of the curve for capital taxes).

But let’s think about what higher tax rates imply, and we’ll focus on the United States. According to the first chart, labor taxes could be approximately doubled before getting to the downward-sloping portion of the curve. But notice that this means that tax revenues only increase by about 10 percent.

This implies that taxable income would be significantly smaller, presumably because of lower output, but also perhaps due to some combination of tax avoidance and tax evasion.

The key factoid (assuming my late-at-night, back-of-the-envelope calculations are right) is that this study implies that the government would reduce private-sector taxable income by about $20 for every $1 of new tax revenue.

Does that seem like good public policy? Ask yourself what sort of politicians are willing to destroy so much private sector output to get their greedy paws on a bit more revenue.

What about capital taxation? According to the second chart, the government could increase the tax rate from about 40 percent to 70 percent before getting to the revenue-maximizing point.

But that 75 percent increase in the tax rate wouldn’t generate much tax revenue, not even a 10 percent increase. So the question then becomes whether it’s good public policy to destroy a large amount of private output in exchange for a small increase in tax revenue.

Once again, the loss of taxable income to the private sector would dwarf the new revenue for the political class. And the question from above bears repeating. What should we think about politicians willing to make that trade?

And that’s the real lesson of the Laffer Curve. Yes, the politicians usually can collect more revenue, but the concomitant damage to the private sector is very large and people have lower living standards. So that leaves us with one final question. Do we think government spending has a sufficiently high rate-of-return to justify that kind of burden? This Rahn Curve video provides the answer.

Mr. Obama’s attack, in a speech during a lunch with editors and reporters from The Associated Press, was part of a broader indictment of the Republican economic blueprint for the nation. The Republican budget, and the philosophy it represents, he said in remarks prepared for delivery, is “antithetical to our entire history as a land of opportunity and upward mobility for everyone who’s willing to work for it.” …“Disguised as a deficit reduction plan, it’s really an attempt to impose a radical vision on our country. It’s nothing but thinly veiled social Darwinism,” Mr. Obama said. “By gutting the very things we need to grow an economy that’s built to last — education and training, research and development — it’s a prescription for decline.”

I’m particularly amused by the President’s demagoguery that Ryan’s plan is “antithetical to our entire history” and “a radical vision.”

Is he really unaware that a small and constrained central government is part of America’s history and vision? Doesn’t he know that the federal government, for two-thirds of our nation’s history, consumed less than 5 percent of GDP?

Of course, that was back in the dark ages when people in Washington actually believed that the Constitution’s list of enumerated powers in Article 1, Section 8, actually enumerated the powers of the federal government. How quaint.

A few other bizarre episodes occurred in Barbados, back when I was first getting involved in the issue. Here’s a summary of that adventure.

As part of its “harmful tax competition” project, the OECD had called a meeting in 2001 and invited officials from the so-called tax havens to attend in hopes of getting them to surrender their fiscal sovereignty and agree to become deputy tax collectors for uncompetitive welfare states.

One of the low-tax nations asked me to provide technical assistance, so they made me part of their delegation. But when I got to the OECD conference, the bureaucrats refused to let me participate. That initial obstacle was overcome, though, when representatives from the low-tax country arrived and they created a stink.

So I got my credentials and went into the conference. But this obviously caused some consternation. Bureaucrats from the OECD and representatives from the Clinton Treasury Department (this was before Bush’s inauguration) began whispering to each other, followed by some OECD flunky coming over to demand my credentials. I showed my badge, which temporarily stymied the bad guys.

But then a break was called and the OECD announced that the conference couldn’t continue if I was in the room. The fact that the OECD and some of the high-tax nations had technical consultants of their own was immaterial. The conference was supposed to be rigged to generate a certain outcome, and my presence was viewed as a threat.

Given the way things were going, with the OECD on the defensive and low-tax jurisdictions unwilling to capitulate, we decided to let the bureaucrats have a symbolic victory—especially since all that really happened is that I sat outside the conference room and representatives from the low-tax jurisdictions would come out every few minutes and brief me on what was happening. And everything ended well, with the high-tax nations failing in their goal of getting low-tax jurisdictions to surrender by signing “commitment letters” drafted by the OECD.

While the controversy over my participation in the meeting was indicative of the OECD’s unethical and biased behavior, the weirdest part of the Barbados trip occurred at the post-conference reception at the prime minister’s residence.

I was feeling rather happy about the OECD’s failure, so I was enjoying the evening. But not everybody was pleased with the outcome. One of the Clinton Treasury Department officials came up and basically accused me of being disloyal to the United States because I opposed the administration’s policy while on foreign soil.

As you can probably imagine, that was not an effective argument. As this t-shirt indicates, my patriotism is to the ideals of the Founding Fathers, not to the statist actions of the U.S. government. And I also thought it was rather silly for the Treasury Department bureaucrat to make that argument when there was only a week or so left before Clinton was leaving office.

I’m reminded of this bit of personal history because of some recent developments in the area of international taxation.

The federal government recently declared that a Swiss bank is a “fugitive” because it refuses to acquiesce to American tax law and instead is obeying Switzerland’s admirable human rights policy of protecting financial privacy. Here are some details from a report by Reuters.

Wegelin & Co, the oldest Swiss private bank, was declared a fugitive after failing to show up in a U.S. court to answer a criminal charge that it conspired to help wealthy Americans evade taxes. …The indictment of Wegelin, which was founded in 1741, was the first in which the United States accused a foreign bank, rather than individuals, of helping Americans commit tax fraud. …Wegelin issued a statement from Switzerland saying it has not been served with a criminal summons and therefore was not required to appear in court. “The circumstances create a clear dilemma for Wegelin & Co,” it said. “If it were to adhere to current U.S. legal practice aimed at Swiss banks, it would have to breach Swiss law.” …Wegelin has no branches outside Switzerland.

It’s time for me to again be unpatriotic because I’m on the side of the “fugitive.” To be blunt, a Swiss bank operating on Swiss soil has no obligation to enforce bad U.S. tax law.

To understand the principles at stake, let’s turn the tables. What if the Iranian government demanded that the American government extradite Iranian exiles who write articles critical of that country’s leadership? Would the Justice Department agree that the Iranian government had the right to persecute and prosecute people who didn’t break U.S. law? Of course not (at least I hope not!).

Or what if the Chinese government requested the extradition of Tiananmen Square protesters who fled to the United States? Again, I would hope the federal government would say to go jump in a lake because it’s not a crime in America to believe in free speech.

I could provide dozens of additional examples, but I assume you get the point. Nations only cooperate with each other when they share the same laws (and the same values, including due process legal protections).

This is why Wegelin is not cooperating with the United States government, and this is why genuine patriots who believe in the rule of law should be on the side of the “fugitive.”
